WILLIAM SCHLERETI-I, OF NEW ROCHELLE, NEW YORK.

SANITARY HYPODERMIC HEATER.

Application filed February 18, 1915.

To all whom it may concern Be it known that 1, WVILLIAM SCHLERETH, acitizen of the United States, residing at New Rochelle, in the county ofWVestchester and State of New York, have invented certain new and usefulImprovements in Sanitary Hypodermic Heaters, of which the following is afull, clear, and exact description, such as will enable others skilledin the art to which it appertains to make and use the same.

The invention relates to heaters for heat ing hypodermic fluid and seeksto provide a simple and effective form of heater which may be carried asthe ordinary watch with fluid bowl inclosed and preserved in a sanitarycondition always ready for instant use.

Doctors of medicine and nurses often find it necessary to resort to thehypodermic in the treatment of patients and usually the swiftness withwhich the treatment can be administered is a very important factor.

Water is the usual absorbent and dissolvent for hypodermic and this mustbe boiled and sterilized to insure the safety of the treatment, thequantity required for one injection being ordinarily about one dram, aconvenient and sanitary means of heating this amount immediately is verydesirable.

The present invention seeks to provide an improved hypodermic heaterwhich may be carried in a closed and sanitary condition, so that bypressing a spring opposed press button the heater is ready for instantuse.

After being used the heater may be closed as readily as the lid of ahunting case watch and carried in the pocket or attached to a chain inthe manner that watches are carried. always ready for an emergency case.

With these and other objects in view the invention consists in thefeatures of construction, combinations and arrangements of partshereinafter set forth, illustrated in the accompanying drawings and moreparticularly pointed out in the appended claims.

In the drawings: Figure 1 is a View of the improved hypodermic heateropened and in position for use. Fig. 2 is a view of the heater in theposition as that illustrated in Fig. 1, but at a different angle. Fig. 3is a sectional view, taken on line a-a of Fig. 4. Fig. 4 is a plan view.Fig. 5 is a fragmentary plan view, with the parts in the same positionas that shown in Figs. 1 and 2.

The inclosing case 1 is preferably a hol- Specification of LettersPatent.

low disk shaped cylinder as shown, one side being closed by the wall 2,the opposite side being provided with the lid 3 hinged at 1 and held inopen position by the spring 5, the lug 6 being suitably shaped to engagethe latch 7 which is held in latched position by the spring 8, the latchhaving mounted on the outward end thereof the push button 9, the spring5 being so arranged as to open the lid and hold it open when the latchis released by pressing the button, the stop 10 of the lid bearing onthe stop 11 of the case and holding the lid when open at an angle ofabout ninety degrees from that of the closed position so that itwillstand upright with the wall 2 lying horizontal.

Projecting from the lid 3 is the lug 12 terminating in the hinge 13 towhich is hinged the fluid bowl 14, the spring 15 being so arranged inthe hinge that it will when not opposed hold the bowl in horizontalposition when the lid is in vertical position as shown.

The lamp 16 is secured to the wall 2 of the heating case and providedwith the hole 17 through which wicking 18 or other absorbent materialmay be inserted to fill the lamp, the absorbent material being saturatedwith alcohol or other fuel, it being obvious that the wicking may besaturated from time to time by pouring fuel thereon, or that the wickingmay be omitted and other forms of fuel may be employed, as urotropintablets which may simply be placed in the lamp and lighted, the resultbeing a steady, hot flame.

The ring 19 is secured to the case 1 for the purpose of attaching achain as to the ordinary watch or a physicians thermometer to preventlosing the heater.

It will be understood from the foregoing that with the lid 3 closed thebowl is held in the position shown with clearance between the bowl andthe lamp, preserving the parts in a clean and sanitary condition, andthat by pressing the push button 9 the lid 3 will instantly open andproject the bowl in position for holding fluid, provided the case 1 belaid with the wall 2 downward. The fluid to be heated is placed in thebowl and a lighted match held underneath, from the heat of which thewater will boil in a few moments, or if desired the lamp may be lightedand the fluid boiled more speedily.

Vhat I claim and desire to secure by Letters Patent is 1. In ahypodermic heater the combination of a case, a lid closing said case,means to open said lid, and means to automatically project a bowl inusable position when said lid is open.

2. In a hypodermic heater the combination of a case, a lid hinged tosaid case, and a bowl hinged to said lid.

3. In a hypodermic heater the combination of a case, a lid hinged tosaid case. a latch suitably positioned to hold said lid closed, a springsuitably arranged to open said lid when said latch is released. a bowlsuitably hinged to said lid,and a spring connecting said lid and saidbowl whereby said bowl may be folded into said case and said spring mayproject said bowl from said lid when said lid is open.

4:. In a hypodermic heater the combination of a case, a lid closing saidcase, a bowl in said case, and means controlled by a push button toautomatically open said lid and project said bowl in usable position.

5. In a hypodermic heater the combination of a case, said case having aclosed side, the opposing side of said case being closed by a lid,' abowl contained in said case, a lamp contained in said case, and meanscontrolled bythe pressing of a pushbutton whereby the lid is instantlyopened to an angle of approximately ninety degrees from said case andsaid bowl is projectedapproximately parallel to said case with said lampin alinement with the axis of said bowl and on the convex side thereof.

6. In a hypodermic heater the combination of a case, a bowl in saidcase, a lamp in said case, a lid closing said case, means for openingsaid lid and means for extending said bowl from said case with said lampp0- sitioned on the convex side of said bowl.

In testimony whereof I afiix my signature in the presence of twoWitnesses.
